I am overseas in Japan. I bought the car listed above, it’s the RA-16 Japanese version. My battery is no longer holding a charge and I need to replace it. However, I can’t seem to find information on what type, since it can’t be an OEM one.
Do you
have the same problem?

Here is a generic guide on how to change out the battery with specific information on your car in the diagrams below. I am not sure about the Japan model this is what they give us in the US. Let me know if you have any questions.

12 00 ... Instructions for Disconnecting and Connecting Battery

Observe safety instructions for handling vehicle battery.

Before disconnecting battery:

Turn off the ignition and other electrical loads/consumers to prevent sparking when reconnecting.

NOTE: If the ignition is not turned off when the battery is disconnected, fault memories may be set in some control units.

IMPORTANT:
- There is a danger of mixing up battery leads: If the battery positive and negative leads are the same color and you are in doubt, follow the polarity to the battery, then mark and cover the leads.
- On vehicles with radio code: After disconnecting the battery, the radio code must be re-entered. Therefore obtain the radio code card from the customer beforehand. Note stored stations and restore them after connecting the battery.
- Stored settings of the on-board computer and clock will also be lost.
- All available central keys must be recoded for cars with first generation infrared transmitter locking systems.

General notes on disconnecting battery:
- Do not disconnect battery leads and leads from alternator and starter motor while engine is running.
- Cars with IBS on battery negative terminal:
Do not under any circumstances pull/lever off pole shoes by force.
Do not under any circumstances release socket-head cap screw of IBS.
- Detach terminal of battery negative lead from car battery and second battery if fitted. Cover battery negative terminal(s) and secure.
- When work is carried out on the electrical system, faults may be caused in the fault memories of some control units when the battery is connected.
- When installing battery terminal: Tightening torque 61 21 1AZ.

After connecting battery:
IMPORTANT:
The scope of application of some systems may be restricted after a power supply interruption.
Likewise, individual settings may be lost.
Settings or activations must be carried out, depending on the equipment specification.

For example:
- Vehicles with automatic engine start stop function (MSA):
MSA function is active only after learning period (vehicle must not be woken for a period of approx. 6 hours) > if necessary, notify customer of the situation
- E46 Perform (four-wheel drive) / E53 / E83: steering angle sensor adjustment
- If necessary, carry out adjustment of active steering
- If necessary, activate slide/tilt sunroof
- If necessary, activate power windows See: Windows > Programming and Relearning
- If necessary, activate mirror with compass

Please refer to the ProDemand user documentation for further information on vehicle-specific activation.

Vehicles with a two-battery system
Starter and system battery

A two battery system has a starter battery circuit and a system battery circuit. An auxiliary control unit monitors both battery circuits. Depending on the situation, the battery circuits are connected to or isolated from the auxiliary control unit via an cut-off relay.

Two AGM batteries, whose design and properties are described in AGM batteries, are used as a storage battery.

IMPORTANT: These batteries must not under any circumstances be charged with a voltage in excess of 14.8 V. Rapid programs must not be used either.

Receiving/giving starting aid via jump start terminal point

The engine can be jump-started with an external voltage supply via the jump start terminal on the right side of the engine compartment.

NOTE: The starter battery is isolated from the alternators when the engine hood/bonnet is open.

Giving starting assistance via the jump start terminal is thus limited by the capacity of the starter battery when the engine hood/bonnet is open.

Charging starter and system batteries via jump start terminal point

The starter battery is charged as a matter of priority with a charger connected to the jump start terminal. The voltage at the starter battery is the decisive factor in determining whether the system battery is also included in the charging operation. The auxiliary control unit automatically detects a charging operation at a charging voltage at the starter battery of e 13.5 V. The cut-off relay is closed and thus the system battery is connected in parallel. Both batteries are now charged.

Prerequisite:
- Terminal 61 inactive
- Terminal 15 inactive

If terminal 15 becomes active during the charging operation, the cut-off relay is opened immediately and again only the starter battery is charged.

NOTE:
When the engine hood is open, the cut-off relay is also opened in normal operation when the engine is running.

A special mode can be set by means of diagnosis for workshop/garage operation. The cut-off relay is closed from terminal R in this operating mode. This mode is automatically reset once a distance of 5 km has been driven.

Trickle charging
The increased standby current consumption can be compensated for via the jump-start connection point with the aid of the Activa easy battery trickle charger (Service Information 2 03 05 205).

IMPORTANT:
The cigarette lighter is isolated from the electrical system after terminal R "OFF" on a timed basis (60 mins.), thereby interrupting charging of the system battery via the cigarette lighter. This is prevented if the battery switch (on the right side of the luggage compartment behind the panel) is turned on and off again twice within 2 seconds. (Cigarette lighter battery charging function).

Check out the diagrams (below). Let us know what happens and please upload pictures or videos of the problem.

This did not help whatsoever. I know how to replace a battery. The question was what battery should I replace it with? I m not able to get one straight from manufacture so I need a comparable type.
